JOHN KELLING, OF MILWAUKEE, WISCONSIN, ASSIGNOR OF ONE-HALF TO ROYAL M.A. IIERZER, OF MILWAUKEE, WISCONSIN.

FLOOR-SCRAPER.

Specification of Letters Patent.

Patented April 23, 1907.

To all whom it may concern.-

Be it known that I, JoI-IN KELLING, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Floor-Scrapers; and I do hereby declare that the following is a full, clear,and exact description thereof.

The invention consists in what is herein shown, described, and claimed,its object be ing to provide simple, economical, and efficientfloor-scrapers each having its bladehead rotary adjustable in eitherdirection at the will of the operator to permit of scraping close tomop-boards or floor-molding, provision being had in connection with saidhead to prevent marring of said mop-boards.

Figure lof the accompanying drawings represents a plan view of afloor-scraper in accordance with my invention, partly broken away; Fig.2, a vertical longitudinal central section of the same; Fig. 3, atransverse section on the plane indicated by line 3 3 in 2; and Fig. 4,a rear end view of said scraper, partly broken away and in section.

Referring by letter to the drawings, A indicates a preferably cast-ironframe having the sides thereof provided with apertures for theengagement of a loose axle B, carrying wheels O, each fastened theretoby a setscrew 1), these wheels being inside said frame. The rear end ofthe frame is provided with de pending bearings c for bolt-spindles E,that serve as axles for wheels F of less diameter than the ones Caforesaid, these smaller wheels being overhung by rear corners of theaforesaid frame. WVashers dare interposed between the wheels O and thebearings for their spindles, and nuts 6 are run on the screw ends ofsaid spindles against said bearings.

The frame, axle, spindles, wheels, and minor parts in the assemblageaforesaid constitute a truck, and loose in end apertures of said framecentral of the truck is a pivot shank G of a head II, having a frontinclined surface upon which to seat a curved edge scraping-blade I, thatis provided with tranverse slots engaged by set-screws f, that engagesaid head, these screws having been passed through apertures in ablade-holder J to bind this holder against said blade when the latter isin adjusted position. The

blade-holder is shown provided with forwardly-projecting sockets g, withwhich elastic buffer-plugs h are engaged.

Riveted or otherwise fastened to a front upper ledge t of thetruck-frame is a semielliptic spring K, that bears at both ends againstthe head H to resist turning of this head in either direction fromnormal position, and held by a set-screw on the rear end of thehead-shank is a clevis L, in which the rounded end of a tang M isfulcrumed, said tang-being held in adjusted position by a sides of theclevis-fork, a clamp-nut m being run on the screw-threaded end of thebolt. Fitted on the tang M is the preferably tubular shank I of a handleN at right angles to said shank, said handle being adjustable to variouselevations to accommodate operators of the scraper.

The truck is normally horizontal, as herein shown, and is tilted forwardto bring the scraper-blade into working position, the scraper as a wholebeing then drawn rearward on its large truck-wheels to effect a scrapingoperation, and by turning with the handle said blade may be canted ineither direction in order to have the same operate close to mop-boardsor floor-molding, this being an important feature of my invention. Thespring K insures return of the head H and parts in connection therewithto normal position when pressure to cant the same in either directionfrom such position is removed.

I claim 1. A floor-scraper comprising a truck, a blade-head having apivot-shank for which the truck is provided with bearings, and a handlein connection with said shank by which to rock said blade-head ineitherdirection at will.

2. A floor-scraper comprising a truck, a blade-head having a pivot-shankmounted in the truck, a clevis having a socket end in which said shankis detachably secured, and a handle attached to the clevis. I

3. A floor-scraper comprising a truck, a blade-head having a pivot-shankmounted in the truck, a clevis having a socket end in which said shankis detachably secured, a tang fulcrumed in the clevis-fork, means forsecuring the tang in adjusted position, and a handle having a shankfitted on said tang.

have hereunto set my hand, at Milwaukee, in GEORGE FELBER.
